David Sloan has spent two years in prison for a murder he did not commit, framed by Tong Po, the drug lord who now keeps Sloan's wife Vicky in Mexico. After explicit photographs of Vicky reach him, Sloan meets the DEA official Casey Ford, who says Po is staging a martial arts tournament inside his private compound, where the champion earns a bout with Po and a million dollars. Ford offers Sloan his release if he enters the contest and takes Po down. Under the alias Jack Jones, Sloan wins a street fight to earn an invitation from the scout Brubaker. On the road he fights off thugs harassing Megan Laurence, another entrant, and at the compound Darcy Cove tells him he must first survive the qualifying matches.
